| Abstract: | The superfine quarried CaCO_3 activated by REC was applied in blown LLDPE mulching film.Within the scope of suitable addition the mechanical properties of the mulching film did not decrease and met the national standards.The mulching film had good openability,obviously improved processability and markedly decreased energy consumption.The covering areas of the mulching film did not reduce,the light transmittance did not lower down,however the cost decreased and good economic benefit could obtain. |
